Radiation Therapy
Radiation therapy uses high-energy rays to damage cancer cells and prevent them from growing. The procedure limits exposure to only those cells in the treated area.
The high-energy rays may come from a large machine (external radiation) or from radioactive materials placed directly in the tumor (internal radiation).
Radiation therapy may be used alone for small tumors or in combination with surgery.
